Be .it known that We, AXEL Regole LYND- B'LAD mdv @we STLHANE, engiueeifs, sub- 'jects of the King of Sweden, residing' et Lud- 5 Vika, io the Kinedom of Sweden, have iiiventeffi new 'and useful Improvements in.

The present invention has for its object to construct environ core fol use in tiausiorme? furnaces, on the basis of the seid observetions, for the purpose of reducing the eekege as fer as possible.

The idee of the inventiou'broedy st'st'tie'd is, that the transformer core is so :(omeo thtts surfaces, as far es possible, eie riot torinesi of the edges of the ioli sheets Wi'ieh constitute the trausomier core, but eie' iiisteed the iron sheets or lemeilse of which the transforme? eoie s formed., so e? eiged that Wherever the leaking Unes of `forge try to esearpe or emenete from the iron core they are oiiiged to pees Le/rossa number of the seid sheets of 533ML in order 'to make om? invention. mo elem, it is described with reference to the' aeeoiipmiying drawing, in which, as esem plee, different oms of the same am il]ustieted F 1 is e front View o1". a recteuguui transformer more constructed according te this vent' m.; Fig. 2 shows e, verticaal @toss section of the same; sbows iu Veieei section e tiensioimei" fui-neue Ciwiuetien fui"neee) provided with another fome. transforme? core eonst'uoted iii. eeeoi' 'with the present ii'iveutiou uid provide-ui with ineens foie cooling the seme; n vei'lieul seetioi'i ou the line A,- und Fig. A t? -U' Fi ,il and, i?, the iioi'i eo mbe? oi' parte or seetoi ,mib thus er seid ff o? the vom@ med, he 9,.

For this purpose the iron oore is provided with :i port orA `opening` 7 through which air jfrom the pipe S moy be introduced into the channelsjand passed through the sii-Ine, whereafter it is 'led oil through the opening 9. tion insulatingT materiel@ is provided between the sections or ports for the purposev above stated..
